Did the savannas have fertile marshes?

Savannas typically consist of grasslands interspersed with trees and do not generally have extensive marshes. However, they may contain localized areas of fertile land near water sources, such as rivers or seasonal ponds, which can support more diverse plant and animal life. These areas can be quite productive and may exhibit marsh-like characteristics, but they are not dominant features of the savanna ecosystem. Overall, savannas are more characterized by their open grasslands than by fertile marshes.
